Abstract
A resilient wire attachment clip has two respective longitudinally extending; elongated, loop portions positioned in two mutually parallel planes, each of the loops formed by an internal limb and an external limb connected by a resilient arc portion that extends through a slot in a housing wall, the external limbs of the two loop portions normally lying within a pair of parallel grooves on the exterior of the housing wall with the ends of the external limbs connected by a transversely extending portion that is spaced outwardly from the housing wall, the internal limbs of the two loop portions have hook-shaped free ends which with slight prestress engage two abutments on the interior of the housing wall to support the clip between the two abutments and the interior surface of the housing wall at the point of an interiorly directed bend in the internal limbs, with the major portion of the diameter of the loop arc portions positioned interior of the housing wall.
